MECHANICAL MOVEMENT.

SPECIFICATION forming part of Letters Fatent No. 444,287, dated January 6 1891.

Application filed October 2, 1890. Serial No- 366,326. (No model .1 I

To all whom it may c0nccrm Be it known that I, ALBIN VVARTH, acitizen of the United States, residing at Stapleton, in the county of Richmond and State of New York, have invented new and useful Improvements in Mechanical Movements, of which the following is a specification.

This invention relates to certain improvements in mechanical movements of that class which is described in Letters Patent No. 172,803, grantedto me January 28, 1876, and which is intended particularly for cloth-cutting machines, but which is applicable to tools of different kinds, such, for instance, as polishing-tools.

The improvements which constitute the subject-matter of my present application are pointed out in the following specification and claims, and illustrated in the accompanying drawings, in which- Figure 1 represents a plan or top view. Fig. 2 is a side view. Fig. 3 is a transverse section in the plane as m, Fig. 1. Fig. 4 is a transverse section in the plane y y, Figs. 1 and 2, on a larger scale than the previous figures. Fig. 5 is a horizontal section in the plane 22', Fig. 4. Fig. 6 is avertical section in the plane a," as, Fig. 5. Fig. 7 is a perspective View of the friction-shoe detached. Fig. 8 is a horizontal section in the plane y y, Figs. 2 and 4. Fig. 9 is a longitudinal vertical section in the plane 2' 2, Fig. 8. Fig. 10 is a plan or top view of a modification. Fig. 11 is a side view of the same. Fig. 12 is a transverse section in the plane a: 00, Fig. 10. Fig. 13 is a similar section in the plane 3 y, Fig. 11, on a larger scale than the previous figures.

In the drawings, the letter A designates a track, which is composed of two bars a a, secured in any suitable .manner at such an elevation from the ground that room is obtained beneath it for the table B and for the tool 0, and the mechanism for actuating the same, as hereinafter described.

On the track A is fitted the carriage D, which has four wheels 01 d on one side, Fig. 2, and a single wheel d on the opposite side, Fig. 1, the wheels 01 01 being made to engage the bar a of the track, while the wheel 01' bears upon the bar a. The axles of the wheels d d have their hearings in the sideplate (1 and the axle of the wheel (1 has its bearing in the side plate (1 and these side plates are connected by transverse bars E F. (Best seen in Fig. 4.) In these bars is secured a tube G, which forms the bearing for the vertical arbor H, and which together wit the cage I forms a hanger that carries the balance-arm J, and this cage I is mounted on the tube G, so that it can freely swivel in either direction. The arbor ll extends through the cage I and through a slotj in the balance-arm, and on its bottom end is secured a pulley h, while on its upper end is firmly mounted a pulley 7b. This pulley is situated between the two branches of the belt K, which extends round a pulley I, mounted on the driving-shaft L, and thence over guide-pulleys 7c 10 70 10 (see Figs. 1 and 2,) the pulley 76 Fig. 2,being mounted in a bracket 70 which is adjustable on a vertical rod k so that by moving this bracket up and down the tension of the belt K can be regulated. The action of the belt K upon the pulley h is controlled by two pulleys 72. 7L2, which are mounted 011 an arm 72/ (See Figs. 1 and 5.) This arm swivels on the upper end of the tube G, and it carries a friction-shoe h, a perspective view of which is shownin Fig.7and which engages a grooved disk h Figs. 5 and 6. This disk turns on the tube G, and itcan be secured in the desired position by a setscrew h, Fig. 5. When the arm 71 is turned to the position shown in Figs. 1 and 5, the branches of the belt K are held in contact with the pulley h on the vertical arbor 1'1 and a revolving motion is imparted to this arbor. The arm h is retained in position by the friction-shoe if, and it can be locked in this position by releasing the set-screw h and turning the disk 7v so that the pin h bears against the pin h Fig. 5. hen the disk 7L5 islocked in this position by the set-screw h, the arm h is positively retained in position, but under ordinary circumstances the friction-shoe h will be sufficient to retain the arm h The balance-arm J is secured to a rockshaft i, which hasits bearingsin two brackets t" i, attached to the bottom plate of the cage I, Figs. 8 and 9, the connection between this rock-shaft and balance-arm being effected by means of a plate j, which is secured to the balance-arm. by a clam ping-screw 3' and which is provided with a lug j that engages the slot in the balance-arm. By these means the balance-arm free to swing in a horizontal and also in a verticalplane, and if the clampmg-screwj is released the balance-arm can be moved in the direction of its length.

The tool 0, which may be a device for cutting cloth or for polishing glass or other material, is attached to the balance-arm .I on one side of its fulcrum, as shown in Figs. 1 and 2, and a weight. M, which is attached to the balance-arm on the opposite side of its fulcrum, serves to counterbalance the weight of the tool. Of course the weight M may be made integral with the balance-arm, or, in other words, the balance-arm may be so formed that it balances the weight of the tool C more or less, according to the position in which it is adjusted on its fulcrum. The pulley h connects by a belt n with a pulley m, mounted on a shaft N, Fig. 1, from which motion is transmitted to the tool. The tube G is screw-threaded externally at its upper end and carries a nut g, arranged within a cup-shaped bearing-piece g, loosely resting on the arm h", Fig. 6. The nut gcan be turned in the bearing-piece for raising or lowering the tube G, whereby the tool C is vertically adjusted for causing its foot-plate to bear ilat upon the table.

In order to be able to use two tools C 0"" side by side, I arrange two single tracks A A, as shown in Figs. 10 to 13, inclusive. In this case the carriages D D are constructed each with four wheels,which engage the tracks A A as shown in Figs. 11 and 12, and from each carriage rises a standard 0 O, which carries two wheels 0 0 0 0', respectively, to engage rails pp,w11ich are fixed overhead. Bythese means the carriages are retained in an up right position and they can be run close together. The balance-arms J J are connected to the carriages D D in the same manner in which the balance-arm J is connected to the carriage D, Figs. 1 to 9, and each of the tools (1 C is geared togcther'with the drivingshaft L in the same manner in which the tool 0 is geared together with the driving-shaft L.

I do not herein claim what is described and shown in my applications, Serial Nos. 363,882, 363,883, and 363,884, filed September 4, 1890.

What I claim as new, and desire to secure by Letters Patent, is-

1. The combination, with the track A, the carriage D, and the main driving-shatt L,

mounted independently of the carriage, of a hanger depending from the carriage, a balance-arm J, mounted in the hanger and free to swing both in a horizontal and in a vertical plane, and a tool carried by the balance-arm and geared with the driving-shaft, substantially as described.

2. The combination, with the track A, the carriage D, and the main driving-shaft L, mounted independently of the carriage, of a hanger depending from the carriage, a balance-arm mounted in the hanger and made adjustable in the direction of its length, said balance-arm being free to swing both in a horizontal and in a vertical plane, and a tool carried by the balance-arm and geared with the driving-shaft, substantially as described.

The combination, with the track A, the carriage D, and the main driving-shaft L, mounted independently of the carriage, of a hanger depending from the carriage, a vertical arbor II, mounted in the hanger, a pulley h, mounted on the arbor II, a belt K, extending from the driving-sh aft L, mechanism, substantially as described, for holding the two branches of the belt K in contact with the pulley h, a balance-arm J, mounted in the hanger and free to swing both in a horizontal and in a vertical plane, and a tool carried by the balance-arm and geared with the arbor ll, substantially as described.

4. The combination, with a depending hanger and with the main driving-shaft L, mounted independently of the carriage, of the balance-arm J, mounted in the hanger and free to swing both in a horizontal and in a vertical plane, and a tool carried by the balancearm and geared with the driving-shaft, substantially as described.

5. The combination, with a depending hanger and with the main driving-shaft L, mounted independently of the carriage, of the balancc-arm J, mounted in the hanger and free to move in the direction of its length and to swing both in a horizontal and in a vertical plane, and a tool carried by the balance-arm and geared with the driving-shaft, substantially as described.

In testi mouy whereof I have hereuu to set my hand in the presence of two subscribing witnesses.
